VoIP (Voice over Internet Protocol)

VoIP is a technology that enables voice and other multimedia to travel over the internet, essentially treating voice as just another form of data. This allows for calls to be made over a computer, smartphone, or other internet-connected device, bypassing the need for conventional phone lines. It's the technology that powers popular services like video conferencing and messaging apps, making communication more flexible and affordable.

Example: A company is developing a new mobile banking app with a VoIP feature for voice authentication during login. To ensure the feature is reliable, the quality assurance team would perform specialized testing. They would simulate poor network conditions, like a slow connection with high jitter, to see if the system can still accurately understand the user's voice command. They would also measure latency to ensure the user's voice is processed quickly enough that the system feels responsive, preventing a frustrating and insecure experience. This process ensures the feature works correctly even when the user isn't on a perfect connection.
